I think this might be in the wrong forum, but since I am using a WRT1900ACv1 running r44467 I am posting the question here.
Now if I navigate to the Administration tab and scroll down to JFFS2 Support then choose 'Enable', choose 'Clean Internal Flash Storage,' click 'Apply Settings', then Reboot the router. The firmware then creates a Partition in the WRT1900AC on-board flash memory. This storage space is then accessed in the DD-WRT file system using the path /jffs.(aka Mounted at /jffs) This is when the Journaling Flash File System is actually managing this storage space.
Does that seem accurate?
So instead of enabling JFFS2 Support as described above I decide to do the following. I navigate to the USB tab of the Services page where I have enabled 'Core USB Support' and enabled 'USB Storage Support.' I have plugged in a USB Storage device into the USB port, or maybe a HDD plugged in via the eSATA port. There is a setting labeled 'Mount this Partition to /jffs' that you enter a UUID number of a partition on an attached USB storage device. That partition is mounted and accessible in the file system in the following path: /jffs.
This is where I find things get a little "fuzzy" based on forum posts and a few different wiki pages.
Now that the firmware has taken the partition on the USB storage device and mounted it to /jffs. (Again I have left JFFS2 Support disabled)
1) After mounting does the firmware also start/enable the Journaling Flash File System to manage that partition?
-or-
2) Is the partition just merely mounted for file system use without any special management?
To me where it says 'Mount this Partition to /jffs' means that it is only mounting the partition without any special management.
Which is correct? Or maybe is there another possibility I haven't considered yet?
